Former President of Mexico Vicente Fox is now trolling President Trump on Twitter.

Back in June 2016 Fox said  he was committed to being Trump’s “shadow until he’s done with politics.” Looks like he meant what he said.

In the last two days, Fox has tweeted about Trump more than a dozen times. He tackles everything from Trump’s views on DACA to tariffs to the economy.

There were also a handful of Spanish tweets targeting Trump as well.
